Physical, mechanical, and structural properties of highly efficient nanostructured n-and p-silicides for practical thermoelectric applications

et al.Cost-effective highly efficient nanostructured n-type Mg2Si 1-x Sn x and p-type higher manganese silicide (HMS) compositions were prepared for the development of practical waste heat generators for automotive and marine thermoelectric applications, in the frame of the European Commission (EC)-funded PowerDriver project. The physical, mechanical, and structural properties were fully characterized as part of a database-generation exercise required for the thermoelectric converter design. A combination of high maximal ZT values of ~0.6 and ~1.1 for the HMS and Mg2Si1-x Sn x compositions, respectively, and adequate mechanical properties was obtained. © 2013 TMS.The work was supported by the EC FP7 Power-Driver Project.Peer Reviewe
